Asia Pacific Partnership Oxy-fuel Working Group
Oxy-Fuel Technology
Conventional pf coal-fired boilers use air for combustion in which the nitrogen from the air dilutes the CO2 concentration in the flue gas. In oxy-fuel technology, combustion with oxygen typically of greater than 95% purity and recycled flue gas is used for combustion of the fuel. By recycling the flue gas, a gas consisting mainly of CO2 and water is generated, ready for sequestration without stripping of the CO2 from the gas stream. The recycled flue gas is used to control flame temperature and make up the volume of the missing N2 to ensure there is enough gas to carry the heat through the boiler.
Currently there are no full-scale plants using oxy-fuel combustion in operation. However, theoretical studies combined with laboratory and pilot-scale studies (typically 30 - 100 MWe) have been announced or are planned, which will lead to commercial deployment.
The Project
The Asia Partnership Partnership project supports an oxy-fuel working group (O-fWG) to coordinate collaboration through information sharing, and joint projects, between oxyfuel demonstrations and support development of the technology towards commercialisation.
Asia Pacific Partnership
The countries comprising the Asia Pacific Partnership are Australia, Canada, China, India, Japan, Korea, and the USA.

The Second Oxy-fuel Combustion Conference (OCC2) was held 13-16th September 2011 in Yeppoon, Queensland Australia. The conference included a tour of the newly retrofitted Callide A Oxyfuel Power Plant. The 3rd APP OFWG Oxyfuel Capacity Builidng course was held on the Sunday evening and Monday prior to the conference (11 & 12th September). The course aimed at providing an introduction to the technology for post graduate students and delegates of the Australian Power industry. For details of the course presentations please follow the course links on this website.
A special Oxyfuel edition of the International Journal of Greenhouse Gas Control is currently being reviewed and will be made available prior to the Second Oxy-fuel Combustion Conference in Yeppoon this year.
Professor Wall will again chair the oxyfuel panel at the Clearwater Coal Conference with Dr Ligang Zhang of CANMET, with presentations on FutureGen 2.0, the Callide Oxyfuel Project and the Vattenfall Projects.
Oxy-fuel combustion for power generation and carbon dioxide (CO2) capture", a hardback book is due to be released in early 2011. Edited by Dr Ligang Zhang of CANMET, the book contains the economics, fundamentals and advanced concepts of oxy-fuel technology. The Oxyfuel Working Group have provided two chapters relating to industrial scale development and heat transfer in an oxyfuel boiler.
An IEA GHG special workshop on SO2, SO3, Hg and Boiler Corrosion under Oxy-fuel Combustion was held 25/26th January 2011 at the Rembrant Hotel in London. Project Leader Professor Wall gave the keynote address on sulphur related issues in an oxy-fuel boiler. Presentations may be viewed from the IEA GHG Oxyfuel Network.
The US Department of Energy has announced that US$1billion will be spent on a demonstration scale oxy-fuel project, FutureGen 2.0, to re-power a pulverised coal fired utility in Illinois. For more information click here
